BUT, it doesn't seem to MOUNT the drive. I have been using an initrd to test.
If you can mount the drive with mount /dev/sda<whatever> <whereever> and it doesn't work with kernel <whatever> root=/dev/sda<whatever>, I can't help you.
But you can try the following:
Code: [Select]
mount /dev/sda<whatever> /media
mount -t devtmpfs none /media/dev
mount --bind /proc /media/proc
mount --bind /sys /media /sys
chroot /media[/quote]

Okay well I type mount --help and it prints a huge block text. My dad has tried to set environment variables to allow for it NOT to print it all at once, unfortunately it doesn't work. Bleh
Keep trying.

Did it work? Also, why do you need to read mount --help?
If you want to know how to use it, you can read http://linux.die.net/man/8/mount, too.

Vog, I was hoping the solution to the problem would apply to everything.
Say I DO get USB working (hypothetically), what would I have to do to boot into it? and is it possible to start from the initrd and then boot into the drive?

Well I've tried what you've suggested and I just can't seem to get it to mount. It may be a problem with my kernel, drive, (I've tried multiple), or even my newer calc model

It (kind of) is. You just have to change "/" to the mountpoint of the drive, which chroot does.

Ooooh I believe I see the problem! (BTW read the above post by me)

My fstab has some very outdated filesystem listings. I need an initrd of a very new build or xconfig, and then I can set things up to my liking. :)
Keep trying.

Hi everybody

I've tried to boot with many rootfs on USB (Debian, Ubuntu, Bodhilinux) and all of them gave me an error about "init not found". The USB device is recognized and mounted. Any idea about how to solve this problem?

Thanks and regards

Tiziano

By default the kernel tries to execute /sbin/init.
Does it exist and have the right permissions?

I have no idea how to compile my own version.. can someone compile a kernel with support for 'screen'? to interact with my arduino.

or teach me how to do it myself.

Thanks

Do you get an error message on executing screen? Or does you initrd not include screen at all?
And why do you need screen for your arduino?

my current version does not have screen. you can communicate with the arduino with screen, if you use cat or echo to the arduino it will reboot, as far as i know screen keeps contact all the time
